Gord,
In an eariler post I suggested you consider downsizing a KR2 instead
of building up a KR 1 for an 0-200. I'll add a few thoughts.
Like Mark L. , I've not seen the KR 1 plans but I think the materials
used are basiclly the same. However, please consider the following.
- You said you are 6'2" with a large upper body. The KR1 is a
SMALL airplane.
- The KR1 was engineered for a VW engine of 30 to 50 hp. The
KR2 is a proven design using the 0-200 and the 2's was
engineered with the 0-200 as a recommended engine.
- In addition to changes to the structure for larger engines, more
weight, etc., I believe the 2's increased the size of the horizontal
tail surfaces for improved handling.
- To me it would be MUCH easier to downsize a KR2 then engineer
up a KR1 and I'd think you'd get equal or better results.
- If I were building it to fit me (6'4"-200 lbs) I'd be inclined to add
maybe 2" to 4" forward of the forward spar to the firewall and maybe
the same aft. I'd recline the seat at a good angle, use maybe
the forward 2/3's of a KR1 bubble canopy and fair it nicely into
a streamlined turtledeck. A "side stick" setup would be nice.
Then I'd drop one of the three Corvair engines I have setting in
my hangar on the nose and I'd have me a "KR Rocket". Is there
a speed limit below 10,000 feet of 250 knots?!! :-)
To restate my eariler conclusion, IF IT WERE ME, and I was looking
for a single place airplane with lots of SPEED and good handling, I'd
narrow a KR 2 to a comfortable single place, keep approx.the same
fuselage length as a standard KR2, cut down the wing span two or
three feet, and incorporate all of the 2's changes along with the
new airfoil. You could weight your nearly completed airframe to
determine the best location for the engine and then build the cowl.
Be advised, I'M NOT AN ENGINEER, so use your best judgement.
